Finite element analysis of deformation mechanism of SiC reinforced 6061 aluminium-based metal matrix composites under compression

The deformation mechanism of SiC reinforced 6061 aluminium-based metal matrix composites (MMCs) under compression is investigated in this study. Finite element analysis was used to examine the impacts of particle size, shape, and content on the stress distribution, stiffness, and strength of MMCs. To identify potential locations of debonding or material failure, the major stress and von Mises strain distributions were displayed. It was found that at 10% reinforcement content the effects of particle size and shape were negligible, however there was an increase in material strength over the monolithic material. The greatest increase to mechanical properties occurred at 20% particle content with the smallest size particle. This was due to an increase in load transfer to the stiffer particles because of increased surface contact length. The reinforcing particles also improved the resistance to matrix material flow. Circular, triangular, square, and rectangular particles were tested. Because of its more evenly distributed strain and greater areas of minimal strain in the matrix material, the rectangular particle provided the highest increase in mechanical characteristics.
